I've received the infamous "Engine Failsafe mode" with a "low oil pressure" warning on start up before but nothing as bad as what happened today.
I'm driving down the road, coming to a red light and as I'm coasting to a stop the RPM's fall flat and the truck stalls out.
I put it in neutral to re-start and it cranks, turns over, runs for a second and shuts off saying low oil pressure. Until I figured out that If I give it some gas the oil pressure and RPM's will stay up and it won't stall out.
Well it stalled 2 more times on the drive home. Just cause I can't be constantly giving it gas.
My only mods are 6" procomp lift and and Edge Evolution set to level 3.
I was getting engine failsafe's long before I had my edge so I didn't think it was that. But to be sure I returned it to stock programming drove it around and it was fine.
At this point I'm hoping it's not my programmer causing the problems, so I put it back on level 3 and it was fine.
So I get in my truck to leave and before I can get out of the driveway the truck stalls out. (it's still set on level 3 @ this point)
So I reprogram to stock and it's fine for the 10 minutes I drove.
Again I'm curious if it's the programmer, so I pull over and re-set it to level 3, drove another 10 minutes and this time it was fine.
WTF is going on? The damn thing can't make up it's mind!!
It's going to the shop tommorow, I'll post back with the problem.
I'm thinking it's gonna need a throttle body and possibly a re-flash.
I'm very angry with Ford right now

 

Why be angry with Ford? Sounds to me like its the edge screwing things up.

I was set to by an edge but ive been seeing to many flukes. Ill hold off for a while.

Hope you get things figured out and let us know back.

 

If it is the edge, did you update to the lastest firm/calib? Aside from the obvious, taking it to the dealer, you need to eliminate all possiblities including Edge's software...I just got one myself and have read many problems with Edge but not what you're experiencing.

 

The low oil pressure at startup is not a "test"? I figured that was normal...

 

You need to put it back to stock and drive it. I don't think it was the EDGE that is causing the problem.

 

I agree on switching it back to stock and driving it but, I must admit, the correlation between uploading your tune and your problems is fairly difficult to ignore.

The flip side of that coin, though, is that I'm not sure I've read a post along these lines specifically referencing the Edge. So -- pretty tough call... Best of luck with getting it squared away and let us know what you hear from the stealership.

The low oil pressure warning will come on whenever the engine stalls or cuts off. Of course there's gonna be low (no) oil pressure if the engine isn't running.

 

Try loading it back to stock and unplugging the Edge from the port under the dash...then completely reinstall the unit via the directions that came with it and you should be fine. Mine did this after I ran Level 2 for a couple weeks and then tried to load level 3. This was the fix I got from Edge and it worked.....

 

Wow.. what a day.
I had 3 mechanics and myself sitting around for 2 hours trying to figure out the problem.
They came to the conclusion that I need a new throttle body and possibly a re-flash.
They couldn't do the reflash there, so they said to take it to a ford dealership.
When I left the shop, it stalled out again not even a 1/4 mile down the road.
At this point I'm thinking it's the Edge (but i'd rather it be something broken that I'd have to pay for to get fixed, because I love this thing)

But, I wanted to be sure so I pulled over, switched back to stock and drove for about 15 minutes, nothing!!
So to be even more certain I pulled over again, reprogrammed to Level 3... accept this time I didn't customize anything, I just used Edge's settings. Drove home about 5 miles and it was working fine, WTF!!!

I'm gonna leave it as is for a while and see if it acts up anymore.
At this point I'm thinking it's level 3 with custom options that is messing everything up.
However, this is all that I have changed:
WOT fuel- 1.6
Octane- 93
Rev- like 5750 or something
Speed limiter- 125 or so
Changed the tire size (I did set it a little bit too low)
and Increased the shift firmeness between 1-2 and 2-3

I don't see how any of that could have caused this problem though.
One of the mechanics was telling me that the ECU isn't really meant to be flashed and re-flashed with programs.
And that it's possible that I had it set at level 3.. wanted custom tunes and went from level 3 to level 3 with custom tunes and that could be causing the problem.
Though he wasn't really sure if the Edge "piggy-backed" or created a whole new program.

At this point i'm thinking that putting it on level 3, then reprogramming to level 3 w/out switching to a different program in between can cause problems.
Which would explain why everytime I set it to a custom tune I had the problem, because i would hit "load previous settings"

But the thing that throws me all of is that my truck did this before... just no where near as bad. I would get the Engine failsafe mode a few times but it would always restart. And it only stalled out on me once vs every other time.

I don't really know wtf the problem is, I just want it fixed.
I have to go to school tommorow, it's like 30 minutes each way, on the way there I'll leave it on Edge's Level 3.
On the way home I'll load my custom options.
I'll post back with the results.

 

You were having this same problem?
Did you edit the custom options?
Should I call Edge and see what they have to say about this?

 

I should have said that....the problem came up when I tried to do the custom tune. I could load the canned tune fine but the custom tune would not load correctly. Like I said all I had to was put it back to stock and unplug it...then reinstall it and it worked fine (even with custom tunes). I read somewhere on here someone else had a problem with the custom tune not loading properly and that was the cure. I tried it and sure enough it worked. Not a single problem since.
I have no idea why it did it...but it worked fine for a month or so. I loaded Level 2 and ran it for a little less then 10 days and then tried to switch back to level 3 an thats when it F'ed up. I thought there was a major problem with the tuner but after finding the "unplugging it" tip it worked find and has ever since. I am guessing the problem has something to do with going from one tune to another and it not resetting properly. I am staying with Level 3 from now on and am very happy with it.
Unplugging it may not work for you but its worth a try!

 

Just want to clarify this.
You were having stalling issues and getting error codes while using a custum options with their cannned tune.
You set it back to stock, un plugged it, set it to level 3 with custom options and it works fine?
I'll try this tommorow and see what happens.
Hopefully this is the problem.

 

Yes...exactly. Canned tune with changes to the gear ratio, rev limiter, tire size and speed limiter. Mine however would stay in "Engine Fail Safe" mode until I loaded the stock tune back. It sounds like yours will be in "normal" mode until it cuts off? Is that right? Mine would never run right with the custom tune installed, but it sounds bascialy like the same thing your describing. Like I said its worth a shot to see if it will fix it.

Mine did show the "Low Oil Pressure" warning but thats when it was cutting off, so I think that was do to the engine dieing rather than an actual code or anything.

 

Assuming you checked your oil level; I would say you need a re-flash or a new tuner.

 

Guys........How the heck can it be the edge? Unless ford put the edge on the truck and gave it to him, its impossible for it to be the edge because it was stalling BEFORE he got the edge....yea
